Analiza pola magnetycznego w silniku liniowym oscylacyjnym oraz obliczanie jego parametrów elektromagnetycznych

The calculation results for a linear oscillating mo- tor have been presented. The motor is designed to be used in mechanical fatigue tests. The thrust, frequency and ampli- tude of the motor moving part (mover) have to be controlled. As the results of the computer simulations the magnetic field distributions under different excitation current values have been obtained and presented. The two components of the magnetic flux density values, in the air gap between inner and outer stator parts, have been depicted. The force values as a function of the coil current and mover position have also been calculated and presented. In the mathematical model, the finite element method (FEM), for magnetic field analysis, has been implemented. The force values have been calcu- lated from Lorentz formula. The target of the studies was to obtain the magnetic force value vs. mover position as con- stant as possible.
